There's a lot going on here: air pressure changes, inertia, and chemical reactions. All of this occurs in 60 seconds time! As an end of the year physical science assessment, consider showing this video clip and then having learners write...

Photo reactive paper is used to do art! You can order this type of paper, have learners place objects on it, and then set it out in the sunlight for a few minutes to create a print. A chemical reaction occurs, driven by light, to turn...

There's not much to this video. Steve Spangler and his twin sons visit 9 News and perform the classic chemical reaction between vinegar and baking soda to produce carbon dioxide gas. Where the value is in this video clip is that they set...

Make a Halloween pumpkin foam at the mouth! Using hydrogen peroxide, toothpaste, and yeast, you can recreate this chemical reaction in your classroom. It can lead to a discussion of the way ingredients mix together to make a new...

Chemical reactions can be beautiful. Show your learners how to make a crystal tree using cardboard, food coloring, Mrs. Stuart's Bluing, ammonia, and salt. Use this activity to demonstrate crystal growth within Earth. The results are...

The light sticks that trick-or-treaters carry at Halloween glow by the process of chemiluminescence, a chemical reaction in which electrons jump to a higher energy level. In this video, the variable of temperature is introduced to find...

Have your class write secret messages using Goldenrod paper and a basic liquid such as ammonia. This is a great way to illustrate the chemical reactions between acids and bases. This could lead to an exploration of chemical reactions and...

An exothermic reaction is demonstrated by showing what happens when hydrogen peroxide reacts with manganese dioxide. It creates the effect used by film makers to have a genie coming out of a bottle in a burst of cloudy gas. Spangler is...

A film canister, Alka Seltzer, and a little water can be an explosive combination. Have your learners try out this chemical reaction in the classroom, and then discuss the results.

In honor of the 4th of July, Steve Spangler shows how to make an explosive concoction in red, white, and blue. Using hydrogen peroxide, dishwashing liquid, and yeast, he creates a colorful chemical reaction. Consider this combination...

This is a classic chemical reaction to use in your science class. Starch and iodine mix to cause a color change. Discuss with aspiring chemists the chemical and physical changes that occur as you demonstrate.

Make your own crystals. Learners can use borax, water, food coloring, and a string to make a colorful crystal. This is a great way to explore chemical reactions, crystal formation, or evaporation.

In honor of the 4th of July, Steve Spangler shows how to make an explosive concoction in red, white, and blue. Using hydrogen peroxide, dishwashing liquid, and yeast, he creates a colorful chemical reaction. Consider this combination...

This is a classic chemical reaction to use in your science class. Starch and iodine mix to cause a color change. Discuss with aspiring chemists the chemical and physical changes that occur as you demonstrate.

An interactive video lesson where students first determine misconceptions about what happens during chemical reactions, and then investigate some various chemical reactions.

What happens when you mix baking soda and lemon juice? Watch the ZOOM cast launch a rocket using kitchen chemistry. [3:26]

Check out this awesome video clip of alkali metals creating an explosion in water. [3:17]

This lesson will show that a combustion reaction is a hydrocarbon burned in oxygen to form water and carbon dioxide. It is 2 of 2 in the series titled "Chemical Reaction Types: Combustion."

This lesson will show how to write a complete ionic equation and by omitting spectator ions a net ionic equation can be written. It is 2 of 2 in the series titled "Chemical Reaction Types: Net Ionic Equation."

Identify an example of graphing first-order rate data to see a linear relationship and calculating rate constant k from the slope. [9:13]

Understand how to derive the half-life equation of a first-order reaction starting from the integrated rate law. [8:12]

A video lecture showing how the equilibrium constant was derived. Follow the derviation using the Haber process as an example. [15:05]

A video lecture giving examples of how to complete stoichiometry problems. The video shows how to calculate the number of grams of each reactant needed to complete the reaction. Also shown is how to determine the limiting reactant in the...
